Deep color is in reference to the use of a greater number of bits to represent the color space on a digital display. Conventional
HDTVs use a subset of the RGB color model (Red, Green, Blue), limiting the color depth to 45% of the possible 16.7 million colors
available in the RGB model when all 24 bits are utilized. With higher bit color spaces such as 32-bit color, the full RGB color space
can be utilized and additional attributes like the degree of transparency of color can be represented, providing more realistic imaging.
HDTVs that utilize “Deep Color” have the ability to display the full color depth of images from sources that make use of broader color spaces,
such as high definition Blu-ray Disc.
xvYCC or Extended-gamut
YCC is a new mathematical model that is being used with high definition video and HDTV to describe color. This method supports 1.8 times the
number of colors that the conventional high-definition television model is capable of providing.
120 Hz refresh
120Hz refresh rate, is a technique used by LCD displays to help to minimize the effects of motion blur we detect when there are
fast moving objects on screen. The technology works by doubling the native refresh rate of LCD displays from 60Hz to 120Hz. The combination of 120Hz refresh rate and improved response times
on LCD panels, has virtually eliminated set based motion blur from LCD HDTVs. If you will be using your HDTV to watch sports, action movies
or play video games, this is a feature you will appreciate.
Response time is a measurement of the time (usually stated in milliseconds) it takes to react to a given input. With LCD panels,
it is the time it takes a pixel to go from active, to inactive and back to active again. If the response time of an LCD panel is too
slow, and you are watching content with fast moving objects, you will see a smearing or blurring of the object(s) as it moves. This
phenomenon, commonly referred to as “motion lag” or “motion blur”, was common on first generation LCD panels. Obviously, the faster
the response, the less likely you are to have response time induced “motion blur”. The ongoing debate surrounding response time, is
how fast is fast enough? CRT’s,
don’t suffer from response time induced motion blur, and the response time on a typical CRT is about 12.5 ms. Most modern LCD HDTVs have
response times below 12.5 ms.

Gamut or color gamut is a subset of colors
The screen image is redrawn 60 times per second
